I've been thinking about the "A" in STEAM a lot lately, and stumbled upon this article. I think that some of scientists' ideas could be communicated better to non-scientists, and that is where ART can play an important role.
From the Scientific American: "Art and science. To those who practice neither, they seem like polar opposites, one data-driven, the other driven by emotion. One dominated by technical introverts, the other by expressive eccentrics. For those of us involved in either field today (and many of us have a hand in both), we know that the similarities between how artists and scientists work far outweigh their stereotypical differences. Both are dedicated to asking the big questions placed before us: “What is true? Why does it matter? How can we move society forward?” Both search deeply, and often wanderingly, for these answers. We know that the scientist’s laboratory and the artist’s studio are two of the last places reserved for open-ended inquiry, for failure to be a welcome part of the process, for learning to occur by a continuous feedback loop between thinking and doing." - John Maeda
